MODE OF ATTAGHING WHIFFLETREES TO VEHICLES.

Specification of Letters Patent No..11,425, dated August 1, 1854;.

To all whom it may concern:

Be it known that I, ABRAM J. GIBSON, of Clinton, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in the Mode of Attaching hiflletrees to vehicles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had tothe annexed drawing, forming part of this specification, in which Figure 1 is a plan of attachment of the Whittle-tree to the axle. Fig. 2 is a side view of the same. i p p The same letters indicate like parts in all the figures.

My invention consists in the attachment of the whiflie-tree to vehicles by means of a steel spring, one end being made fast to the whitlie-tree, and the otherin the center and front of the forward axle. The advantage gained by this mode of attachment is, that it allows of a suflicient motion to the whitlle- I tree, in the draft, and makes a safe, perma nent, and durable attachment. In the usual mode of attachment, the motion of the draft is brought upon the bolts or straps which connect the Whittle-tree with the vehicle, causing them to wear and get loose; whereas, in my mode of attachment, the motion of the whiiile-t-ree, in draft, is communicated directly to the center of the spring.

Having pointed out the nature of my in vention, and some of the advantages to be derived from the same, I will now proceed to describe its several parts, reference being had to the annexed drawing, in which, 6 represents the forward axle, in the perch, d the whiflieetree, and e the springof steel or other suitable elastic material, which connects the Whittle tree and forward axle b, by means of bolts and clasps passed through and around the sidearms, f of the said spring 6.

The advantage to be derived from this attachment, besides those previously mentioned, is, that the cross bar which is usually used to connect thethills together, and to which the whifile-tree is attached, is dispensed with, and the Whittle-tree attached directly to the forward axle Z) by means of A. J. GIBSON.
